Science
Mechanism of Action
As an anionic surfactant derived from phosphate esters, Potassium Laureth Phosphate primarily functions as a detergent, efficiently breaking down and emulsifying dirt, excess oil, and other impurities for thorough rinsing. It simultaneously acts as an emulsifier, stabilizing oil and water components within a formula. Its mild, effective foaming and skin-conditioning properties ensure a refreshed, smooth, and hydrated feel post-cleansing.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that alkyl phosphates, including Potassium Laureth Phosphate, are safe when formulated to be non-irritating and used at current concentrations. While animal studies at significantly elevated concentrations demonstrated potential irritation, these levels are far beyond typical cosmetic applications. A maximum concentration of 8.7% for related alkyl phosphates in rinse-off products is reported, serving as a guideline for safety. There is no specific SCCS opinion available, and its FDA status as a food additive (GRAS) does not directly pertain to cosmetic product use.
